[Simultaneous hepatic cholangiocarcinoma and bone fibrosarcoma 45 years after ingestion of Thorotrast].

This case of a 63 year old man reports the simultaneous development of hepatic cholangiocarcinoma and fibrosarcoma of the sacrum 45 years after the systemic injection of Thorotrast. The characteristic radiologic aspect was an important criteria for diagnosis. Biopsies have confirmed the histology of both tumors. We describe the way to thorotrastosis diagnosis and characteristic malignant tumors, especially cholangiocarcinoma, induced by Thorotrast.

Erythropoietin umbilical serum levels during labor in women with preeclampsia, diabetes, and preterm labor.

In this study we determine the erythropoietin levels and hematocrit in 22 women with preterm labor, 21 with insulin-dependent diabetes, 22 with preeclampsia, and 20 with normal gestation. The erythropoietin level was higher in the preeclamptic group than in the diabetic group compared with the normal and premature groups. There were no hypoxic fetuses. From this study, we found that the mechanism of increased erythropoietin levels in neonates can be different from fetal hypoxia. Further studies are needed on this subject.

Follicle cyst formation after administration of different gonadotrophin-releasing hormone analogues for assisted reproduction.

The aim of this study was to examine the occurrence of ovarian cysts during the administration of three different gonadotrophin-releasing hormone analogues (GnRHa) in the long protocol as well as their characteristics, management and outcome compared with patients with no cyst formation. A total of 172 in-vitro fertilization (IVF) cycles in which GnRHa was administered at menstruation were analysed. Group B consisted of 72 cycles in which buserelin was used. Of these, 10 (13.9%) were with cysts (group B1) and 62 (86.1%) without cysts (group B2). Group T included 49 cycles in which triptorelin was injected. Of these, seven (14.2%) were with cysts (group T1) and 42 (85.7%) without cysts (group T2). Group L comprised 51 cycles in which leuprolide was administered. Of these, eight (15.7%) were with cysts (group L1) and 43 (84.3%) without cysts (group L2). All women with ovarian cysts had higher serum oestradiol concentrations and all except five underwent cyst aspiration with no complication. No differences were observed in the number of follicles and oocytes between groups B, T and L or between the groups with cysts and those without cysts. The pregnancy rate was similar in all groups. In conclusion, follicle cyst formation does not seem to be related to the use of a specific GnRHa, its short- or long-acting form or to the mode of administration. In addition, follicle cyst aspiration is a safe and successful solution to the problem of functionally active ovarian cysts.

[Acute myelitis after vaccination against hepatitis B].

A 56-year old man was hospitalized for spasmodic paraparesis with sphincter disorders. After exclusion of spinal cord compression and all other inflammatory, infectious or neoplastic causes, the possibility of a connexion with an hepatitis B vaccination performed with a recumbent vaccine three weeks before the neurological disorders appeared was considered. The pathogenesis of such a myelitis remains uncertain. It is based on the possible reactivation of a dormant virus or a crossed antigenic reaction between a protein of the vaccine and the nervous system. The course of the disease is usually favourable. The frequency of this complication would be more accurately determined if all neurological manifestations occurring after hepatitis B vaccination were reported.

Growth hormone, oestradiol, progesterone and testosterone concentrations in follicular fluid after ovarian stimulation with various regimes for assisted reproduction.

Follicular fluid samples and oocytes were obtained from 75 women (87 cycles), who participated in an assisted conception programme. Determinations of the concentration of oestradiol, progesterone, testosterone and growth hormone were performed in all follicular fluid samples. Patients were stimulated with the following regimes: group A (24 cycles, 94 samples), human menopausal gonadotrophin (HMG) (three ampoules/day) and human chorionic gonadotrophin (HCG); group B (23 cycles, 53 samples), HMG/HCG with prednisolone (7.5 mg/day) after cycle programming with oral contraceptives; group C (40 cycles, 60 samples), buserelin with HMG/HCG. Oestradiol concentrations (mean +/- SEM) were significantly higher (P < 0.05) in group A (320.1 +/- 27.3 ng/ml) and those of growth hormone in both groups A and C (3.8 +/- 0.2 and 3.2 +/- 0.15 ng/ml, respectively), as compared to the other groups, whereas progesterone and testosterone concentrations were similar in all groups. The mean concentrations of oestradiol, progesterone, testosterone and growth hormone were significantly higher (P < 0.01) in follicular fluid with oocytes of intermediate maturity than with mature oocytes (382.5 ng/ml, 7847.5 ng/ml, 1704.5 ng/dl and 3.7 ng/ml versus 217.8 ng/ml, 5488.4 ng/ml, 1313.6 ng/dl and 2.7 ng/ml, respectively). On the other hand, only oestradiol concentrations were significantly higher in follicular fluid of fertilized compared to non-fertilized oocytes. Concentrations of the other hormones analysed, except growth hormone, were similar in follicular fluid from pregnant and non-pregnant women after assisted reproduction. Growth hormone, on the other hand, was significantly lower (P < 0.05) in follicular fluid from pregnant compared to non-pregnant women (2.8 versus 3.5 ng/ml).(ABSTRACT TRUNCATED AT 250 WORDS)

Acute renal failure in pregnancy.

Between 1982 and 1992, 18 cases of pregnancy-related acute renal failure (PR-ARF) were observed (9% of the total number of ARF). Mean age of the women was 32 years (22-40 years). Uterine hemorrhage and preeclampsia/eclampsia were the major causes of ARF, accounting for 61% of the cases. Patchy renal cortical necrosis was suspected in 2 cases whereas signs of disseminated intravascular coagulation (DIC) or microangiopathic hemolytic anemia were present in 6 (33%) and 9 (50%) cases, respectively. Ten women required hemodialysis; and 6 of them, additional plasma exchange sessions. Five patients (28%) died during the acute phase of the illness, mainly due to brain damage, hepatic failure, and sepsis. Among the survivors, a complete (61.5%) or partial recovery (23.1%) was usually seen, but irreversible renal failure was recorded in 2 cases with postpartum hemolytic uremic syndrome (HUS). Short-lasting oligoanuria (< 3 days) represents a good prognostic index. However, the presence of vascular injury (cortical necrosis, HUS) seems to carry a poor prognosis. In conclusion, PR-ARF is still a critical occurrence, associated with serious prognosis for both women and kidneys. So far, the most effective measures remain the careful prevention and the aggressive management of the obstetric complications.

[Gastrobronchial fistula].

A-79-year old man, treated by thoracic fundoplication for hiatus hernia with symptomatic gastroesophageal reflux, 12 years previously, was examined for persistent cough and left basal pneumonia. Esophagogastroscopy revealed a gastrobronchial fistule which was confirmed by endoscopical fistulograms. Surgical treatment led to complete recovery of the patient. A review of the literature confirms the rarety of this ailment as well as the relevance of preoperative diagnosis by perendoscopical fistulograms.

Acute uric acid nephropathy in pregnancy.

BACKGROUND: Although uric acid clearance increases during gestation, uric acid nephropathy is a rare cause of acute renal failure in the pregnant woman. CASE: A 38-year-old woman experienced acute renal failure due to acute uric acid nephropathy at 30 weeks' gestation. The diagnosis was based on extreme hyperuricemia and an elevated uric acid-creatinine ratio. Treatment with forced diuresis, urine alkalinization, and mannitol infusion resulted in a prompt and complete recovery of renal function. The woman ultimately gave birth to a healthy child. CONCLUSION: Acute uric acid nephropathy during pregnancy responds to conventional medical therapy.
